Electron-Beam Technology in the Processing of Hafnium Ingots

Abstract

In 1986In -1987 in Ukraine, the UE-177RL electron-beam device is tested to process ingots of hafnium with the productivity of 10 tons/year. Wasteless processes of cutting and refining the ingot surface with an electron beam successfully replace cutting the ingot on a planer with a cutter and processing the surface of the hafnium ingot on a lathe. This makes it possible to increase the yield of hafnium from the alloy by 8-12%, depending on the geometry of the ingot, to reduce the amount of chips, to remove the surface defects of the ingot, to obtain a melted layer corresponding to ASTM.
